Mortality in the United States — Provisional Data, 2023

Final annual mortality data from the National Vital Statistics System for a given year are typically released 11 months after the end of the calendar year. Provisional data, which are based on preliminary death certificate data, provide an early estimate of deaths before the release of final data. In 2023, a provisional total of 3,090,582 deaths occurred in the United States. The age-adjusted death rate per 100,000 population was 884.2 among males and 632.8 among females; the overall rate, 750.4, was 6.1% lower than in 2022 (798.8). The overall rate decreased for all age groups. Overall age-adjusted death rates in 2023 were lowest among non-Hispanic multiracial (352.1) and highest among non-Hispanic Black or African American persons (924.3). The leading causes of death were heart disease, cancer, and unintentional injury. The number of deaths from COVID-19 (76,446) was 68.9% lower than in 2022 (245,614). Provisional death estimates provide an early signal about shifts in mortality trends. Timely and actionable data can guide public health policies and interventions for populations experiencing higher mortality.


Introduction
The National Center for Health Statistics' (NCHS) National Vital Statistics System (NVSS) collects and reports annual mortality statistics using U.S. death certificate data.Because of the time needed to investigate certain causes of death and to process and review death data, final annual mortality data for a given year are typically released 11 months after the end of the calendar year.Provisional data, which are based on preliminary death certificate data sent to NCHS, provide an early estimate of deaths before the release of final data.NVSS routinely releases provisional mortality data for all causes of death, including deaths involving COVID-19.*This report NCHS coded the causes of death according to the International Classification of Diseases, Tenth Revision, which details disease classification and the designation of underlying cause of death § (2).COVID-19 death counts and rates include deaths for which COVID-19 is listed on the death certificate as an underlying or contributing cause of death.¶ Leading causes of death were ranked by counts based on underlying cause of death (3).Data in this report exclude deaths among residents of U.S. territories and foreign countries.Age was unknown for 71 (<0.01%) decedents, and race and ethnicity were unknown for 10,068 (0.33%).

Data Analyses
To describe the trend in deaths during a given year, the number of deaths were calculated for each week from all causes and from COVID-19.Age-adjusted rates were calculated for deaths overall and by sex, and race and ethnicity.Crude death rates were calculated by age.The population data used to calculate death rates are July 1, 2023, estimates based on the blended base produced by the U.S. Census Bureau (4,5).Unless otherwise specified, comparisons made in the text among rates are statistically significant (p<0.05 using a z-test).R software (version 4.0.3;R Foundation) was used to conduct all analyses.This activity was reviewed by CDC and was conducted consistent with applicable federal law and CDC policy.**§ https://www.cdc.gov/nchs/nvss/manuals/2a-sectioni-2021.htm¶ The underlying cause of death is the disease or injury that initiated the train of morbid events leading directly to death.A contributing cause of death is a disease or injury also listed on the death certificate, that is not classified as the underlying cause of death.

Overall Measures
In 2023, a total of 3,090,582 deaths occurred in the United States (Table ).The age-adjusted rate was 750.4 deaths per 100,000 population, a decrease of 6.1% from 798.8 in 2022.The number of deaths was highest during the week ending January 7 (68,965) and during the week ending December 30 (65,257) (Figure 1).In 2023, death rates per 100,000 were lowest among persons aged 5-14 years (14.7) and highest among persons aged ≥85 years (14,285.8),similar to patterns in 2022 (Table ).Death rates decreased from 2022 to 2023 for all age groups (although not significantly for ages 0-4 years).Age-adjusted death rates in 2023 were higher among males (884.2) than among females (632.8), and lower than in 2022 (males = 954.5;females = 666.1).
Age-adjusted death rates per 100,000 in 2023 differed by race and ethnicity and decreased from 2022 to 2023 for all groups (Table ).Rates were lowest among multiracial (352.1) and highest among Black persons (924.3).The three leading causes of death were heart disease (680,909 deaths), cancer (613,331), and unintentional injury (222,518) (Figure 2).The number of deaths attributed to unintentional injury were tabulated using the internal NVSS mortality database and might not match publicly available provisional counts for deaths for unintentional injury because provisional data on injury-related causes of death are publicly released with a lag of 6 months from the date of death.This delay accounts for the additional time typically needed to report injury-related death certificates, and the final 2023 death count might be higher than noted in this report.Overall death rates and COVID-19-associated death rates decreased from 2022 to 2023 for all demographic groups (but not significantly for ages 0-4 years).Although the overall and COVID-19 death rates decreased from 2022 to 2023 for persons aged ≥85 years, rates for this group remained higher than those for all other age groups.Overall and COVID-19-associated death rates decreased for all racial and ethnic groups.In 2023, White and AI/AN persons had the highest COVID-19-associated death rate (19.6 and 18.7, respectively), a shift from 2020−2022 when COVID-19 death rates were highest among AI/AN persons (1,6,7).

The estimated age-adjusted death rate, 750.4 per 100,000 persons, was 6.1% lower in 2023 than in 2022 (798.8)(1).Death rates were highest among males, older adults, and Black persons.The highest weekly numbers of overall deaths and COVID-19 deaths occurred during early January and late December.The leading causes of death in 2023 were heart disease, cancer, and unintentional injury.COVID-19, the fourth leading cause of death in 2022 became the 10th leading cause in 2023.COVID-19 was the underlying cause for 1.6% of all deaths in 2023, decreasing from 5.7% (186,552 deaths) in 2022.Deaths from heart disease decreased in 2023 compared with 2022 (702,880 deaths), and deaths from cancer increased from 2022 (608,371).
